meta-bletchley: phosphor-virtual-sensor: add virtual HSC_Input_Power
- Virtual_P12V_AUX_HSC_Input_Power
Apply calibration equation to adjust HSC Input Power
HSC sensor reading have error with the measurement from pin directly,
those errors are different to each actually power measurement,
use linear interpolation to estimate error in each range of HSC POWER reading.
